I'd like to pick you up on an important point if I may. You state...
“Because of the seriousness of the punishment [for adultery] the requirement of proof is huge too, you need 4 witnesses”
So by your own admission, you need at least four witnesses in an adultery case. Correct?
Where did this rule come from? Oh yes, Mohammed – his favourite wife, Aisha, was accused of cheating (on her polygamous husband). Three witnesses corroborated the event, but Muhammad did not want to believe it, and so established the arbitrary rule that four witnesses are required.
So why then have you previously denied that Islamic law needs four witnesses to a adultery/rape case? (Note to none Muslims: Women who allege rape, without the benefit of the act having been witnessed by four men who subsequently develop a conscience, are actually confessing to having sex. If they or the accused happens to be married, then it is considered to be adultery. Ergo, you need four witness for both adultery or rape – the evidential “four witnesses” requirement is same in either case).
